Couldn't in sentence A means "I was not able to" It is not possibility at all. It is inability. Could have in sentence B means possibility in the past.

  • Couldn't in sentence A means "I was not able to" It is not possibility at all.

  • When you were in New York, you could have stayed with my brother.

If I say, " I talked to him because I could hear him clearly ",does it mean I was able to hear him(showing ability in the past).
